# Replace Product in Video > To replace a product in a video with AI, upload the clip to Kenerate Genjutsu, choose Swap object, add a clean packshot of your product as @image1 and write "swap the bottle for the product in @image1". The new product takes the old one's place, scale and movement in every frame, including when hands hold or turn it.

Quick variants of a 6–15 second social ad, one per product. - Kenerate Genjutsu Pro (Kenerate): Clip 2–15 s + up to 10 references → 480p, 720p or 1080p · ~3–6 min. Close-ups where glass, metal or fabric texture must read cleanly. - Seedance 2.5 (ByteDance): Clip 4–30 s + up to 30 references → 480p to 4K · ~4–8 min. Ads up to 30 s, up to 30 packshot angles, and 4K for big screens. ## Steps 1. Pick the source take — The product clearly visible and not tiny in frame. MP4, MOV, WebM or M4V up to about 100 MB; 2–15 s, or up to 30 s on Seedance 2.5. 2. Prepare the packshot — Your product alone on a plain background, sharp, in the same orientation as in the clip. Add side and back views as @image2, @image3. 3. Choose Swap object and name the old item — "Swap the white bottle on the counter for the product in @image1." Naming the old item matters when there are several. 4. Keep the original audio on — Voice-overs, music and sound effects stay aligned with the action, because the timing doesn't change. 5. Compare, then make the next variant — Check the label and hand contact in the synced compare view, download, and run the same take again for the next product. ## In depth ### Preparing a packshot the engine can copy The Swap object instruction asks the engine to match the reference's shape, material, colour, texture and details, so the packshot is effectively the brief. A slightly boring, accurate photo beats a stylised campaign render. - One product per image, nothing else in frame. - Plain, light background and even studio light. - Same angle the product shows in the clip. - Extra angles as @image2, @image3 for turns. - Real colours — no heavy retouching or glow. ### Labels, small text and compliance copy Generated video handles form and colour far better than small type. A big wordmark on a can usually holds; a nutrition panel, a batch code or an ingredient list may come out blurred or rewritten. Plan for it: keep the label face large in the source shot, and put any copy that must be exact — claims, prices, legal lines — on top in your editor after the swap. ### Placement, disclosure and fair comparison Using AI to update your own ads is ordinary post-production. The line is crossed when an edit changes what someone appeared to endorse or use: swapping a product into a creator's clip without a deal, or replacing a rival's product to stage a comparison. Get written agreement for creator content and disclose paid placements as advertising. ### When to reshoot instead A swap can't fix a product of a very different size or shape — a tall bottle where a lipstick was, or a laptop in place of a phone — because hands, shadows and framing were built around the original. Swap object also needs something to swap: it isn't built to place a product on an empty table. If the new product needs a different interaction, a new take is quicker. ## FAQ Q: Can AI replace a product in an existing video? A: Yes. Genjutsu's Swap object mode replaces one named item with the product in your reference image, matching its shape, material, colour and details. The new product keeps the original's exact place, scale, orientation and movement in every frame, with contact, occlusion, reflections and shadows, while people, hands, background and camera stay unchanged. Q: Will my label and logo come out exactly right? A: Large shapes, colours and bold logos usually carry over well; small text, ingredient lists and fine print may not be reproduced letter for letter. Review every frame in the compare view. For legal copy, prices or claims that must be exact, add them as a graphic overlay in your editor after the swap rather than relying on the generated label. Q: What is AI product placement? A: It means putting a product into footage after it was filmed instead of on set. Genjutsu does this by replacement: it swaps an item already in the shot for your product, so the hands, the table and the light are already right. It works best when something of a similar size already sits where your product should be. Q: Which shots work best for a product swap? A: Shots where the product is clearly visible, not tiny in frame, and moves at a moderate pace. Slow pushes, turntables, hand-held reveals and pours all work. Very fast whip pans, products mostly hidden by fingers, and items reflected in mirrors are harder — check those moments first in the synced compare view before you approve a variant. Q: Does the voice-over stay in sync after the swap? A: Yes, by default. Keep the original audio is switched on, and the swap doesn't change the clip's length, motion or timing, so voice-over, music and sound effects line up exactly as before. Turn it off only if you want new sound generated to match the edited scene; Dub into another language is also available afterwards. Q: Can I put my product into a creator's or influencer's video? A: Only with their permission and the rights to the footage. Edit videos you own or licensed, swap only products you're entitled to show, and never replace a competitor's product to make it look like a creator endorsed yours. Paid placements should be disclosed as advertising — in the US the FTC's Endorsement Guides apply. ## Related pages - AI Video Editor: https://kenerateai.com/ai-video-editor - Swap an object in a video: https://kenerateai.com/swap-object-in-video - AI product ads: https://kenerateai.com/product-ads - UGC ads: https://kenerateai.com/ugc-ads - Video background changer: https://kenerateai.com/video-background-changer ## Sources - Kenerate Genjutsu (video editor): https://kenerateai.com/app/genjutsu - FTC — Endorsement Guides: What People Are Asking: https://www.ftc.gov/business-guidance/resources/ftcs-endorsement-guides-what-people-are-asking
